Juski was found guilty of "felony aggravated stalking, misdemeanor loitering and resisting arrest," prosecutors in Miami-Dade County told TMZ.

According to E!, Jurski first appeared in court in December after breaking into a restricted area backstage at the American Airlines Arena in Miami. He initially faced "misdemeanor charges of loitering and resisting arrest."

Jurski allegedly proceeded to follow Perry across stops in Orlando, Tampa, Atlanta, Chicago and Grand Rapids, and even tried to get through to her during two shows in Canada.
